Soaps Detergents
Consist of a ‘-COONa’ group attached to a fatty acid having a long alkyl chain. Consist of a ‘-SO3Na’ group attached to a long alkyl chain.
They are not effective in hard water and saline water They do not lose their effectiveness in hard water and saline water.
Soaps are completely biodegradable Detergents containing a branched hydrocarbon chain are non-biodegradable
They have a tendency to form sum in a hard water environment. These compounds do not form scum.
They are derived from natural sources such as vegetable oils and animal fats. Detergents are synthetic derivatives.
Soaps are environment-friendly products since they are biodegradable. These compounds can form a thick foam that causes the death of aquatic life.
Examples of soaps: sodium palmitate and sodium stearate. Examples of detergents: deoxycholic acid and sodium lauryl sulfate.

Reverse osmosis is osmosis in which it have a container in which semipermeable membrane is present in the middle of the solution and solvent. When the force or pressure is applied on the solution side then the molecules of solvent is passed through semipreamble membrane to solvent from this process the particle which have less size 10 to power minus 9 or 10 to the power minus 10 NM Is passed from SPM. Pure water is obtained in the right side which is solvent..

When the external pressure applied on the more concentrated or solution side is greater than the osmotic pressure on the dilute or pure solvent side,then the flow of solvent takes place from the solution to the pure solvent side. This is called reverse osmosis. =)

the movement of fresh water through a semipermeable membrane when pressure is applied to a solution on one side ....

Yukti Verma 5 years, 7 months ago

It is defined as the flow of solvent from solutions to pure solvent through semi permeable membrane

Ayushi Mishra 5 years, 7 months ago

The direction of osomosis can be reversed if a pressure larger than the osomotic pressure .Then, now the pure solvent flows out through tje semipermeable membrane. This phenomena is called reverse osmosis

If pressure more than osmotic pressure is applied then reverse osmosis takes place and is used in desalination of sea water

Meghna Thapar 5 years, 7 months ago

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules and larger particles from drinking water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.

In biochemistry, the substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.

Aluminum sulphate has most no of particles after dissociation are 5

Gaurav Seth 5 years, 7 months ago

potassium sulphate

Urea and glucose do not dissociate in solution. Sodium chloride gives two ions and potassium sulphate gives three ions per formula unit.
Therefore, the effective number of particles is maximum in potassium sulphate , and it shows the maximum depression in freezing point.

I think the answer is 11 since neopentyl chloride is 1-chloro 2,2-dimethylpropane.Primary hydrogen is the one which is attached to primary carbon(carbon attached to another single carbon) and here there are 9 primary hydrogen atoms in the three CH3 groups surrounding a carbon + two hydrogen atoms attached to the CH2 group attached to Cl and one carbon.

Raoult's law (/ˈrɑːuːlz/ law) is a law of thermodynamics established by French chemist François-Marie Raoult in 1887. It states that the partial pressure of each component of an ideal mixture of liquids is equal to the vapour pressure of the pure component multiplied by its mole fraction in the mixture.
